On Tuesday, Dwayne “The Rock” Johnson wrote a post on Facebook about his annoyance with some of his “candyass” male co-stars on the set of Fast 8. Because he named no names, we were left to speculate, with many fans guessing that the Rock’s beef was with Fast & the Furious newcomer Scott Eastwood. How wrong we were...

According to TMZ, the Rock has actually been bumping shiny heads with franchise veteran Vin Diesel for the duration of Fast 8's shooting:

Production sources tell TMZ...Vin finished filming his scenes, with The Rock, no less, at 1 AM Wednesday and almost as soon as the director called cut Vin gathered everyone and said he was leaving. During his speech he said, “Daddy’s gone” ... Vin thinks of himself as the father figure on set.

Our sources say earlier in the day, Vin confronted Rock over the disparaging comments he made about his male co-stars. Although Rock didn’t name names, we know he was referring to Vin.

We’re told Vin went to Rock’s trailer and demanded to know why he was talking trash. The 2 spoke privately inside but we’re told they did not squash their beef. One source intimately familiar with the actors tells us it’s all about big egos.
